NWT Vix Paula Hermanny swim suit cover up

Size small. My husband bought me this and I noticed that the arm holes are Sewn shut. I reached out to the company who advised me this was their product and to either return it or try to open it myself which I don’t feel comfortable doing as I don’t want to ruin a great product and it didn’t fit me the way that I had hoped. Looking for the right owner and home who this will work for! Only reasonable offers will be accepted.
